Nesta dissertação estudamos extensões pn-cíclicas de um anel comutativo R de característica p, com p primo, via vetores de Witt. Além disso damos uma descrição Z/pnZ - módulo Tn(Z/pn Z, R) das classes de isomorfismos de extensões pn- cíclicas de R.In this dissertation we atudy cyclic pn-extensions af a commutative ring R of characteriatic p (where p is a prime integer) via Witt vectors. Moreover, we give a descript.ion of the Z/pnZ-module Tn(7L/pn Z, R) o{ the Úlomorphism classes of cyclic pn -extensions of R
